One of the classic problems joining many of the geoscience disciplines is the relationship between ice sheets, sea level and the solid Earth during glacial cycles:  Geophysical modelling defines the solid Earth’s response to changes in surface loads and hence constrains estimates of mantle rheology;  geological observations provides constraints on past ice movements and on the sea level response to the changes in the ice loads; geodetic data provides measures of the recent response to past and present ice changes; glaciology provides the observational evidence and theory for ice movements in a changing climate; and the dynamics of the solar system provides one of the driving forces for the growth and decay of ice sheets.  It provides therefore not only a scientific challenge but also insights into the working of the climate system of the planet, and a framework for discussing human migrations and coastal archaeological settings. 

Here, I will endeavour to give an overview of where this science is at: what have we learnt about past ice sheets from geophysical inversions of geological data; what have we learnt about the mantle’s response to surface loading on time scales of thousands of years; are realistic palaeo reconstructions possible of the coastal zones; and are there lessons that may be relevant to understanding present sea level change.
